No, because electrons do not reside in the nucleus. But if you are wonder if the Number of electrons and protons effect the atom then yes, it does. You must have a equal number of electrons and protons but as for the stability of the atom, electrons won't mess the nucleus up.
In 0.7L (700ml) there are 122, 85 grams of NaCl
C=0.184 mol/L
n=0.113 mol
n=CV
V=n/C
V=0.113/0.184=0.614 L = 614 mL
The energy of the photons is
<h3>Energy of Photons</h3>
The formula for calculating the energy of photons is expressed as:
where
- h is the Plank constant
- c is the speed of light
- λ is the wavelength
Substitute the values into the formula to have:
Hence the energy of the photons is

Answer:
24.5g
Explanation:
Given parameters:
Mass of oxygen gas = 21.8g
Unknown:
Mass of water = ?
Solution:
This problem deals with the decomposition of water;
Reaction equation;
2H₂O → 2H₂ + O₂
2 mole of water will produce 1 mole of oxygen gas
First find the number of mole of the oxygen gas given;
Number of moles =
molar mass of O₂ = 2(16) = 32g/mol
Number of moles of O₂ = = 0.68moles
1 mole of oxygen gas will be produced from 2 mole of water
0.68moles of oxygen gas will be produce from 0.68 x 2 moles of water; = 1.36moles of water
Mass of water = number of moles x molar mass
Molar mass of water = 2(1) + 16 = 18g/mol
Mass of water = 1.36 x 18 = 24.5g
